Julien, first, make sure you are using the Open MPI wrapper which mpifort should be /usr/lib/openmpi/bin if i understand correctly then make sure you exported your LD_LIBRARY_PATH *after* you prepended the path to Open MPI lib in your .bashrc you can either LD_LIBRARY_PATH=/usr/lib/openmpi/lib:$LD_LIBRARY_PATH export LD_LIBRARY_PATH or directly export LD_LIBRARY_PATH=/usr/lib/openmpi/lib:$LD_LIBRARY_PATH
then you can ldd ./test and comfirm all MPI libs (both C and Fortran) are pointing to Open MPI Cheers, Gilles On Tue, Nov 15, 2016 at 9:41 PM, Julien de Troullioud de Lanversin <j.detroulli...@gmail.com> wrote: > Hi all, > > > I am completely new to MPI (and relatively new to linux).
